JOURNAL-BOX FOR ARMATURE-SHAFTS.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed November 3, 1910. Serial No. 590,419.

county, New York, have invented certain new and useful Improvements in Journal- Boxes for Armature-Shafts, of which the following is a specification.

Our invention relates to improvements in journal boxes, and our improvements are more especially desi ned for journal boxes adapted to be used For the armature shafts of dynamos employed in electric car light- "ing systems in which the dynamo is driven by the movement of the car.

One object of our invention is to provide a journal box which shall not only be more simple and economical in operation and construction and more eflicient generally, but

which is so constructed that easy access is had to the interior thereof and suitable means are provided whereby the waste or other lubricant conductor will not pack and whereby suitable oil channels for thefree flow of oil or other lubricant are provided.

Further objects, features and advantages will more clearly appear from the detailed 1 description given below, taken in connection with the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a side view of a journal box embodying one form of our improvements; Fig. 2 is a vertical lonitudlnal section of the ournal box shown in Fig. 1, taken on the line II-II of Fig.

3; Fig. 3 is a vertical transverse section of the same taken on the line III-III of F ig. 2, and Fig. t is a horizontal longitudinal section taken upon the line IV--IV of Fig. 3.

Referringto the various figures. 1 represents a suitable framework or casing adapted to be suitably supported to the magnet frame of the dynamo and for this purpose it is provided with bolt holes 2. The casing is provided with a suitable lubricating chamber 3 having a bottom 4 and a top 5. The lubricating chamber is provided on one side with an opening 6 covered by a door 7 hinged at 8. The shaft is shown at 5), and on the other side of the shaft 9 the lubricating chamber 3 is provided with an opening 10 covered by a plate 11 secured to the parts of the chamber by means of bolts 12. The

, ber 17 forms an opening through the member 17 so that the oil feeding waste may rest upon the top of the shaft 9 to properly lubricate the same.'

Adjacent the chamber 3 and arranged about the shaft 9 around the bearing 15 is an oil slinging chamber 18, rovided with an opening 19 through which t e shaft 9 passes, the opening 19 being somewhat larger than the shaft 9. Adjacent the chamber 3, but on the opposite side thereof from the chamber 19 is a second oil slinging chamber 20 si'ipilarly surrounding the shaft 9 and having an opening 21 through which the shaft 9 passes, the opening being somewhat larger than the shaft 9. Keyed or otherwise secured to the shaft 9, within the chamber 18, is a grooved circular member 22 for slinging the oil from the shaft 9. Similarly secured to the shaft 9 and situated within the chamber 20 is a second grooved circular member 23 for slinging the oil within the chamber 20.

Located along the inside bottom of the chamber 3 and integral therewith, we provide a series of ribs 24, 25, 26, 27, 28. 2S) and 30. The ribs 24:, 26, 27 and 29 extend nearly to the center of the bottom of the chamber 3 where they terminate as at 31, leaving longitudinal oil channels, so that the oil can pass from one side of the ribs to the other.

The ribs 25 and 28 do not extend so near the center of the bottom of the chamber 3, but terminate at points 32 and 33, as clearly shown in Fig. 4. Intermediate the prints 32 and 33 lies the rib 30 and free oil channels are left between the ends of the rib 30 and the points 32 and 33.

The ribs 27, 28 and 29 are each provided with integral upwardly extending portions or projections 34. These projections 34 ektend upwardly between the shaft 9 and the opening 6 or door 7, but are so spaced from each of these as to leave a suitable space between them and the shaft 9 for waste or other oil carrying substance and so as to leave a suitable space as at 35 (Fig. 3) between the projections and the door 7 and side of the chamber 3, sothat this space acts as a free oil space.

The end side 13 is provided with vertically arranged integral ribs 36, which lie directly below the shaft 9 and extend in planes substantially vertical with the shaft 9 to prevent the waste or other material from packing. Likewise the end side 14.- is provided with a similar rib 37 and with an enlarged rib 38, similarly situated. The rib 38 is provided with a duct 39, opening into the chamber 3 at a point 40, a short distance below the shaft and leading out of the chamber 3 and journal box at 41. (Fig. 3.)

A duct 42 leads from the lower part of the oil slinging chamber 18 into the chamber 3 and a duct 43 leads from the bottom part of the oil slinging chamber 20 also into the chamber 3. r

The. operation and detail arrangement will clearly appear from the following: The journal box is suitably charged with waste or other oil or lubricant conducting material, the same being forced over the top of the bearing member 17 and down beneath the axle 9, resting upon the ribs 24, 25. 26, 27, 28, 29 and 30. The chamber 3 is then suitably filled With oil up to the point 40. Any excess oil will run out of the chamber 3 through the duct 39, which acts as an over flow to limit the height of the oil within the chamber 3. 3 I

The ribs 24; to 30, inclusive, act to space the waste away from the bottom 4 of the chamber 3 and to form free oil channels therebetween so that the circulation-of oil throughout thewhole bottom part of the chamber 3 is not obstructed. In this connection, it is noted that the ribs 24 to 30 extend transverse the axle 9, thereby forming oil channels extending in a similar mamier.

and the spaces between the ribs 24. and 29,

25 and 30, 26 and 27, and between 28 and 30 form free oil channels extending longitudinally with respect to the axle 9. The side ribs 36, 37 and 38 act to prevent the waste from packing. The projections 34 keep the waste away from the door 7 and that side of the chamber 3, so that the operator may readily place his fingers in the opening 6 and down into the space 35 and ascertain if there is sufficient oil in the journal box. In this respect it is noted that the height of the oil at the point 40 is such that when one places his fingers in the space 35 he will feel the oil if it is at its proper height.

' The shaft in rotating picks up the oil from the waste and it is thereby properly lubricated. The oil on the shaft will, of course, run along the axle and when it comes to the members 22 and 23 it is carried to the edges of said members by centrifugal action. The grooves in said members prevent the oil from traveling longitudinally farther along the axle and the centrifugal action throws or slings the oil oil the members 22 and 23 into the chambers 18 and 20 respectively. The oil, therefore, collects in the bottoms of the chambers 18 and 20 and runs back again into the chamber 3 through/the ducts 42 and 43, where it is again utilized. The outer portion of the casing 2 shown at 44., is designed to contain the pole changer of the dynamo for which the journal box is used.

Although we have described our improvements in great detail, nevertheless we do not desire to be limited to such details except as clearly specified in the appended claim, since many modifications may be made well within the spirit and scope of our invention.

Having thus fully and clearly described our improvements, what we claim as new and desire to secure by Letters Patent is:

In ajournal box for shafts, a suitable lubricating chamber, having integral circumferential ribs on the inside of the lower part of said chamber extending in planes substantially at right angles to the axis of the shaft so as to form oil channels in the bottom of the chamber, said chamber having an openingtherein on one side of the shaft, said ribs having upwardly extending integral projections spaced from the sides of the chamber adjacent said opening, an. opening in said chamber on the opposite side of the shaft from said first mentioned,

opening, integral ribs on the sides of said chamber and extending substantially vertically beneath the shaft to the bottom'of the chamber and an oil overflow duct in one of said ribs leading out of the chamber, oil slinging chambers, one on each side of said lubricating chamber and ducts leading from said oil slinging chambers to saidlubricating chamber.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribin witnesses.
